The prophesied Armageddon that had some believing Saturday, Sept. 23 would end the world came and went over the weekend without incident. But infamous conspiracy theorist David Meade — who rose to viral fame last week in connection to the purported rapture — has recalibrated Doomsday and now predicts Oct. 15 could be when the “action starts” and when the world will enter into a seven-year “Tribulation period.”

Meade previously asserted that the significance of 33 in numerology and its relation to the recent solar eclipse should be considered when calibrating the end of the world, thus where the Sept. 23 date originated. An alleged planet called Nibiru was expected to collide with Earth on the date and obliterate all life.

“Jesus lived for 33 years. The name Elohim, which is the name of God to the Jews, was mentioned 33 times [in the Bible],” Meade told the Washington Post in an interview last week. “It’s a very biblically significant, numerologically significant number. I’m talking astronomy. I’m talking the Bible … and merging the two.”

Meade, a Christian numerologist, now writes that nothing “is expected to happen in September.” Instead, Meade has provided a more vague approximation for when Doomsday will strike on his website.

“The major signs that converge on September 23 are indeed amazing, but those are celestial events. They are time markers,” he wrote. “The mainstream media states that something visible will occur on these dates. I don’t believe that.  The actual event of the beginning of the Tribulation occurs on October 15. That’s when the action starts. Hold on and watch – wait until the middle of October and I don’t believe you’ll be disappointed.”

Meade wrote that October will be the “month to watch” and called the 15th in particular “the day of the onset of the 7-Year Day of the Lord, or Tribulation.”

While Meade continues to pedal his conspiracy theories that appear loosely based on a confluence of questionable metrics, experts at NASA say otherwise. The space agency commented on last week’s headline-grabbing Doomsday prediction in a blog update on a past response to why the world didn’t end as prophesied in 2012.

“Various people are ‘predicting’ that world will end Sept. 23 when another planet collides with Earth. The planet in question, Niburu, doesn't exist, so there will be no collision,” NASA wrote. “News flash: the world didn't end on Dec. 21, 2012. You've probably already figured that out for yourself. Despite reports of an ancient Maya prophecy, a mysterious planet on a collision course with Earth, or a reverse in Earth's rotation, we're still here.”
